Template helpers (bottle_utils.html)

Contents of this module are mostly meant to be used inside the view templates, but their usage is not limited to templates by any means. bottle_utils.html contains a few data-formatting functions as well as shortcuts for generating HTML snippets and binding data to form fields.

Basic usage

One way to make the module contents available to templates is to add the module itself as a default template variable.:

import bottle
from bottle_utils import html
bottle.BaseTemplate.defaults['h'] = html

This allows you to use the module members by access the h variable in templates:

<html {{! h.attr('lang', request.locale }}>

Note

If your tempate engine auto-escapes HTML, you need to instruct it to unescape strings gneerated by some of the helper functions. For instance, in Bottle's SimpleTemplate engine, you need to enclose the strings in {{! }}.
